The bacterial flora of blue crabs (Callinectes sapid us) from Chesapeake Bay was examined. Hemolymph of normal, healthy blue crabs was found non-sterile, with total bacterial counts ranging from <100 to >3.0 x 10 5 on a seawater-based medium and 0 to >10 5 on Standard Methods Agar. Counts of 0-10 3 were observed on TCBS agar. Vibrio spp., including Vibrio parahaemolyticus, were the major taxono...

conclusions the results showed that although the human gut microbiome plays a pivotal role in health in a normal concentration, fluctuation in their number (increase or decrease) is a possible factor in the appearance of major diseases. context the composition and function of the gut microbiota develop with their host from birth. the human microbiome, especially the gut microbiota, plays a crit...

In order to study the bacterial flora of dead-in-shell ostrich chicks, twelve unhatched eggs which did nothave external pipping during the hatching period were transferred to the laboratory of microbiology. The eggshells were accurately disinfected and the embryos were removed and placed in a sterile plate. The surface of each embryo was swabbed with a sterile swab which was also plunged throug...

AIM To study the role of intestinal flora in inflammatory bowel disease (IBD). METHODS The spatial organization of intestinal flora was investigated in normal mice and in two models of murine colitis using fluorescence in situ hybridization. RESULTS The murine small intestine was nearly bacteria-free. The normal colonic flora was organized in three distinct compartments (crypt, interlaced, ...

The normal bacterial flora contains antibiotic resistance genes to various degrees, even in individuals with no history of exposure to commercially prepared antibiotics. Several factors seem to increase the number of antibiotic-resistant bacteria in feces. One important factor is the exposure of the intestinal flora to antibacterial drugs. Antibiotics used as feed additives seem to play an impo...

OBJECTIVE To determine the conjunctival bacterial flora present in patients with Stevens-Johnson syndrome. METHODS A prospective study of the conjunctival bacterial flora was performed in 41 eyes of 22 patients with Stevens-Johnson syndrome. The information gathered included the patient's sex and age, the duration of disease, the cause of Stevens-Johnson syndrome, and treatments. Scrapings of...

Intensified aquaculture includes the use of antimicrobials for disease control. In contrast to the situation in livestock, Escherichia coli and enterococci are not part of the normal gastrointestinal flora of fish and shrimp and therefore not suitable indicators of antimicrobial resistance in seafood. In this study, the diversity and phenotypic characteristics of the bacterial flora in raw froz...

A prospective observational study was conducted at J. N. Medical College, Aligarh Muslim University, to compare the bacterial flora obtained from sequestrum culture and sinus track culture and to evaluate their antibiotic sensitivity. A total of 62 patients with chronic osteomyelitis were enrolled (38 males and 24 females). Sinus track cultures were done taking all aseptic precautions and the r...

Bacterial infection, especially with intestinal-type bacterial flora, is a common complication in patients with cirrhosis [1–4]. Spontaneous bacterial peritonitis (SBP), urinary tract infection, pneumonia, spontaneous bacterial empyema and bacteraemia are the most frequent infective complications in this group. The incidence of infection with Gram-positive cocci, in particular, has increased in...
